OAuth HMAC-SHA256 signature method.

OAUTH_AUTH_TYPE_AUTHORIZATION (string)

This constant represents putting OAuth parameters in the Authorization header.

OAUTH_AUTH_TYPE_NONE (string)

This constant indicates a NoAuth OAuth request.

OAUTH_AUTH_TYPE_URI (string)

OAUTH_REQENGINE_STREAMS (integer)

OAUTH_REQENGINE_CURL (integer)

Used by Oauth::setReqeustEngine() to set the engine to Curl, as opposed to OAUTH_REQENGINE_STREAMS for PHP streams.

OAUTH_OK (integer)

Life is good.

OAUTH_BAD_NONCE (integer)

The oauth_nonce value was used in a previous request, therefore it cannot be used now.

OAUTH_BAD_TIMESTAMP (integer)

The oauth_timestamp value was not accepted by the service provider. In this case, the response should also contain the oauth_acceptable_timestamps parameter.

OAUTH_CONSUMER_KEY_UNKNOWN (integer)

The oauth_consumer_key is temporarily unacceptable to the service provider. For example, the service provider may be throttling the consumer.

OAUTH_CONSUMER_KEY_REFUSED (integer)

OAUTH_INVALID_SIGNATURE (integer)

The oauth_signature is invalid, as it does not match the signature computed by the service provider.

OAUTH_TOKEN_REVOKED (integer)

The oauth_token has been revoked, and will never be accepted.

OAUTH_PARAMETER_ABSENT (integer)

A required parameter was not received. In this case, the response should also contain the oauth_parameters_absent parameter.
